Their appearances are currently unknown, as they wear Solrock and Lunatone masks.

Sol sounds male, and has a generally stoic personality. He has a very weak telekinesis, suited for little more than watchmaking or lockpicking; however, secure locks tend to be Psychic-proofed, so Merkle often handles the latter on missions.

Ton sounds female, and is perhaps Sol's sister. She's more hotheaded, and quick to personally intervene when she dislikes the tide of a Pokémon battle.

Their Breloom, BreBre, is prone to making up hammy ways to use Solarbeam, and has a grudge against vampires.

Origins

Little is known about their origins except that they originally came from Alola, and their old home was demolished by Best Berry.
